OEM Carrier Direct Spark Ignition (DSI) Control Board LH33WP003 for Model PY1PPB036060ABAA

This is the genuine OEM Carrier Direct Spark Ignition (DSI) control board, part number LH33WP003, factory-specified for the Carrier PY1PPB036060ABAA packaged rooftop unit. As the brain of your system's heating sequence, this integrated control board manages spark ignition, gas valve activation, combustion blower and indoor fan motors, flame sensing, and safety lockout — all in a single microprocessor-driven module. When this board fails, common symptoms include a no-heat condition, repeated ignition lockout faults, short-cycling, or a system that sparks but never establishes a stable flame.

  • Specs: Direct Spark Ignition (DSI) integrated control board | Manages combustion, blower, and indoor fan motor sequencing | Onboard flame sensing and trial-for-ignition timing | Microprocessor-based with LED fault code diagnostics for faster troubleshooting
  • OEM vs Generic: This is a genuine Carrier OEM board built to exact factory specifications. Aftermarket substitutes may omit proprietary timing sequences or safety interlocks unique to Carrier rooftop units, risking nuisance lockouts or voided equipment warranties.
  • Install difficulty: 3/5 — Disconnect all power and gas before servicing. Photograph all wiring harness connections and terminal labels before removing the old board. Tools needed: flat-head and Phillips screwdrivers, needle-nose pliers, multimeter. Verify 24V control circuit is intact before powering up. Recommended for qualified HVAC technicians.
  • Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse — get your unit back online fast.

Compatibility: Designed for the Carrier PY1PPB036060ABAA packaged rooftop unit. Also fits select Carrier, Bryant, and ICP commercial rooftop platforms that use the LH33WP003 DSI control board — confirm your unit's existing part number against your data plate before ordering.

Frequently Asked Questions

Does this Control Board fit my Carrier PY1PPB036060ABAA?
Yes. This is the factory-specified OEM control board for the Carrier PY1PPB036060ABAA. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.
How do I replace the control board on my Carrier PY1PPB036060ABAA?
Difficulty: Advanced (1–2 hrs)
Step 1: Turn off breaker. Step 2: PHOTOGRAPH all wire connections before touching anything. Step 3: Label each wire with tape. Step 4: Disconnect all wires, remove old board. Step 5: Mount new board, reconnect all wires matching your photo exactly. Step 6: Restore power and test all modes. Exact part number match is critical.
My HVAC system is completely dead. What could be wrong?
Completely dead HVAC (no LED on board) = failed control board or blown fuse. Check board fuse first (3A or 5A, costs $1–$5). If fuse is good and board has power but no LED, board is dead. Always photograph wiring before replacing.
Is this control board compatible with Bryant or Payne too?
Many Carrier parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.
Should I use OEM or aftermarket for my Carrier control board?
OEM essential. Control boards are model-specific with precise firmware and connector layouts. Aftermarket boards rarely match all functions and can cause intermittent failures or safety issues. Always match the exact OEM part number.
How fast does National HVAC Parts ship?
